Example; Installing Option Cards In The Inverter - Fronius Primo 3.0-1 Instructions De Service

After cutting out because of overcurrent or undervoltage, the inverter attempts to restore
the power supply in the Fronius Solar Net every 5 seconds while the fault is still present.
Once the fault is rectified, power to the Fronius Solar Net will be restored within 5 seconds.

Example

Recording and archiving data from the inverter and sensor using a Fronius Datamanager
and a Fronius Sensor Box:
Data network with 3 inverters and a Fronius Sensor Box:
- Inverter 1 with Fronius Datamanager
- Inverters 2 and 3 without Fronius Datamanager!
The external communication (Fronius Solar Net) takes place on the inverter via the data
communication area. The data communication area contains two RS 422 interfaces as in-
puts and outputs. RJ45 plug connectors are used to make the connection.
IMPORTANT! Since the Fronius Datamanager functions as a data logger, the Fronius So-
lar Net ring must not include any other data logger.
Only one Fronius Datamanager per Fronius Solar Net ring!
Any other Fronius Datamanagers must be removed and the unoccupied option card com-
partment sealed off using the blanking cover (42,0405,2020 - available from Fronius as an
optional extra); alternatively, use an inverter without Fronius Datamanager (light version).
Installing option Information on installing option cards in the inverter and connecting the data communica-
cards in the in- tion cable can be found in the installation instructions.
